IMPROVEMENT IN STEAM-JET APPARATUS FOR FORCING ANDEXH'AUSTING AIR ANDCONDENSlNG STEAM.

Specification forming part of Letters Patent No. 142,856, dated Sepkn1b(-r-l(i, 1873; application filed April 14, 1873.

' tus for forcing and exhausting air and condensing steam, adapted for avariety of uses,

but intended more especially for blowing smiths fires, exhaustinggas-retorts, and condensing the exhaust steam from steam-engines. Theinvention, consists in so constructing the apparatus that it maybevaried in capacity according to the demands upon it; and in anarrangement for removing all moisture from the air-blast.

Figure 1 is a central section of myapparatus adapted for blowingor-forcing air; Fig. 2, a section of the same with the air-dryingapparatus connected thereto; Fig. 3, a' section of the apparatus adaptedfor exhausting instead of blowing air; and Fig. 4, a section of theblower, and drying apparatus :applied to the exhaust'port oi. an engine.

The apparatus by which the air is set in motion, whether it is tohel'orccd forward or exhausted, consistsot' a steam-nozzle, A, a munberof receiving-nozzles, l3, and alarge flaring or diverging tube, 0,arranged in line with eachother, so that the steam jet passes throughthem all. The nozzles are mounted in abody, l), and are so arranged thatthe small end of each one extends slightly into the large end of thenext, so that annular spacesa are left between. them for thevadmissionof airn The nozzles are surrounded and held by partitions I), whichdivide the-bodycinto several chambers, each of which is provldedwith anopening, 0, to admit air from the outsule, so that each nozzle has aseparate independent communication-with the outsideair. Each openin g eis provided with a hinged valve, (1, opening inward, so that by mea s eVMYGS each nozzle may have its communication-with atmosphere closed orshut off w thout affecting the others. When a. full head of steam 18used, and the apparatus is working-up to itsfull capacity, the steamblows forward through all the nozzles, and causes a strong andcontinuous current of air through the openings 0 and spaces a into allthe nozzles B, and forward into the tube 6. hen, however, it is requiredto have the apparatus move only a small quantity of air, and the supplyof steam is therefore reduced, it will be insufficient' to cause asuction or current into all the nozzles. There will be a suction intothe first one,two, or more of the nozzles, according to the quantity andpressure of steam but from the others there will be an outward currentor pressure, which will close their valves (1, and thereby shut ofttheir communication with the atmosphere and render them inoperative. Bythus closing the communication of one or more of the nozzles with theair the apparatus'is reduced to the same capacity it would have withoutthem, and enabled to operate on a small scale; whereas, if the valveswere removed, it would be impossible to work the apparatus, except witha jet of steam suflicient to cause a suction into all the nozzles, forthe reason that the air and steam, instead of passing forward into thetube 0, would escape' from the inner nozzles into the air."

Instead of usin g the autom atic hinged valves, the same object may beaccomplished by mount.-

-ing a sliding sleeve or valve, (1, around'thc body D,'as shown in Fig.3, so that when moved forward it will cover and close the air-inlets c.

As before stated, the arrangement used for used-for exhausting air thebody D is inclosed" in a casing, G, and the exhaust or suction pi poconnected to the casing, as shown in Fig. 3, so that the air will bedrawn from the casing through into the nozzles, and driven out throughthe tube (J. The apparatus, whether intended for blow-' ing orexhausting, maybe operated by live therefrom. In the latter case thesteam, while it serves to operate the apparatus, will, in turn, becondensedjby the inflowing cold air. The

apparatus serves as acheap and efficient condenser, and may therefore beused for that purpose alone when it is not desired to employ itfor'e'ither of the other purposes.

When the apparatus is to be used for blowing smiths fires, or for otherpurposes which require a dry blast, I pass the blast through a body ofcoke, charcoal, or like material, which will absorb and retain themoisture. I arrange the material in a body, H, between two perforatedplates, h and i, leaving chambers above and below the material; and Ipass the air-pipe down through the material into the bottom chamber, andthen apply another pipe,

L, to the upper chamber to carry the air off.

The air, entering the bottom chamber, passes up through the material and011' through pipe. L in a dry and pure conditiomwhile the moisture orwater is retained by the material, and falls "back! into the bottomchamber, from whence it passes out through a siphon, M.

When the apparatus is applied to an engine, as in Fig. 4, the air may beused for anysnitable purpose, and the water pumped back into the boileragain.

It is obvious that in constructing my appa, ratus the form andarrangement of the valves may be varied as desired, and that the bodycontaining the drying or, absorbing material may beco'nstructed in any'suitable -manner without departing from the limits of my invention. Whenthe apparatus is applied to an engine it is not necessary to use thevalves, or

to givethe nozzles separate communications nozzles and the air may beclosed, when 0011- structedand arranged to operate substan tial] y asherein shown and described.

2. In'eombination with a steanrblowing or exhausting apparatus,substantially such as herein described, a body containing coke,

charcoal, gravel, or like material, so arranged that the air passesthrough said material, and is deprived of moisture thereby.
